I think you should give the phone back to the owner and try getting your money back because this might be a permanent problem , and the phone might have been used by the owner and he might have made an account on the iPhone . If you want to save money by keeping the phone , you can set up a appointment with The Apple Store and they might be able to help you out ! I hope this helps you , good luck .

Combine the radicals. 2√24+5√54 A) 53√6 B) 5√6 C) 19√6 D) 93√6
love history [14]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

2√24 + 5√54

To combine the radicals first make sure the radicals have the same square root

That's

<h3><u>For 2√24</u></h3>

<h3>2 \sqrt{24}  = 2 \sqrt{4 \times 6}  = 2 \times 2 \sqrt{6}</h3><h3>= 4 \sqrt{6}</h3><h3 /><h3><u>For 9√54</u></h3>

<h3>5 \sqrt{54}  = 5 \sqrt{9  \times 6}  = 5 \times  \sqrt{9}  \times  \sqrt{6}</h3><h3>= 5 \times 3 \times  \sqrt{6}</h3><h3>= 15 \sqrt{6}</h3><h3 />

Since they have the same square root we can combine them

That's

<h3>4 \sqrt{6}  + 15 \sqrt{6}  = (4 + 15) \sqrt{6}</h3>

We have the final answer as

<h2>19 \sqrt{6}</h2>

Hope this helps you

\frac{4}{9} ÷ \frac{2}{3}

First, apply the rule: a ÷ \frac{b}{c} = a × \frac{c}{b}
\frac{4}{9} × \frac{3}{2}
Second, apply the rule: \frac{a}{b} × \frac{c}{d} = \frac{ac}{bd}
\frac{4x3}{9x2}
Third, multiply 4 × 3 to get 12, and 9 × 2 to get 18.
\frac{12}{18}
Fourth, find the GCF of 12 and 18.
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 18: 1, 2, 3, 6, 9, 18
The GCF is 6.
Fifth, divide the numerator by the GCF. 
12 ÷ 6 = 2
Sixth, divide the denominator by the GCF. 
18 ÷ 6 = 3
Seventh, rewrite your fraction.
\frac{2}{3}

Answer as fraction: \frac{2}{3}
Answer as decimal: 0.6667
